Dan Crispin, August 21, 2018

Hands down best price. Finally glad to see an extender that's affordable. I didn't fit well into Phallosan, so it was nice to have one-size fits all with PhalloGauge. I'm uncircumcised (uncut) so I'm glad the double-grip method works so well with PhalloGauge. Definitely recommend if you've been frustrated with other penis extenders.

Judd Salvio, September 7, 2018

A bit pricy but definitely worth it. I first tried SizeGenetics and Phallosan. Phallosan's condom parts didn't fit my penis well, so it always slipped off. The SizeGenetics was OK, but I got the cheap version and the noose part always choked out my penis. Not to mention I'm uncircumcised and I had issues getting it stay on. Sizedoctor did not have any of these issues, so I'm glad I switched over and finally found an extender that's not wasting my time.

Phallosan's Big Problem: Sizing Issues

Each Phallosan comes with a small, medium and large condom part.

broken phallosan condom part

Phallosan condom part also breaks easily.


However, most men will find they will not fit perfectly into one of the three sizes.

If the condom part is too small, it chokes your penis. If it's too big, you may slip out of the device.

As a result, Phallosan is simply not usable.

Penis Extender Reviews

Here's one in-depth review of the top 4 penile extenders:

#1. PhalloGauge Penis Extender™

Here are the reasons why it is one of the best ones for length gains:

  • It is completely invisible when worn.

  • It is one-size-fits all. No sizing problems.

  • Designed for both circumcised and uncircumcised men (double-grip technology).

  • Awesome, unbeatable price.

The PhalloGauge eliminates slippage with, stretchy silicone "double-grip" wrap technology.


To see more reasons on how the PhalloGauge extender has improved upon length size technology check out this page here.

At $115, there's no denying that the price of the PhalloGauge Extender is one that a lot of men rely on.

#2. PhalloSan Forte

Price: #339 + $25 shipping.

PhalloSan is similar to PhalloGauge but is definitely not ideal for stretching.

Phallosan uses a vacuum condom to hold the tip in place to extend.

PhalloSan Penile Extender Issues

Some male user reviews have reported irritation at the tip of the penile glans due to the Phallosan vacuum.

The Phallosan vacuum is a neat idea, however, some men's penises are just too sensitive and can't handle it.

For this reason, we cannot accept it as the best extender.

Here we cut open the pieces of the Phallosan for analysis.

Here, we cut open the parts of the PhalloSan to see what it is made of.

Vacuum Condom Penile Sizes

PhalloSan extenders come in 3 different condom sleeve sizes - small, medium, and large.

For example, I chose a "medium" size because "small" size was way too tight and it was painful.

One problem I soon found, is that you might actually fit between sizes.

For example, I fit between a small and medium Phallosan vacuum condom sleeve size.

As a result, the extender kept slipping off.

This is a problem that users expect not to happen.

Finding one best size is a challenge.

PhalloSan Extender Best Price? Heck no.

Phallosan is well over $300. Yikes.

And that doesn't even include shipping costs (which are also high because they ship from Switzerland.

Given the issues I ran into, it is hard to truly recommend this extender to men. Don't buy.

Go here to read the full review on the PhalloSan Forte.

#3. SizeGenetics

Price: $200+ (Varies slightly with bundle picked)

SizeGenetics is actually not that bad.

Sizegenetics is essentially a size toy like the Jes Extender and X4labs extenders.

But the SizeGenetics is more popular than the x4labs extenders.

There are a few problems with Sizegenetics.

In fact, it's probably the best one out of the old length extenders.

One thing we will say is that the noose system is probably the most comfortable out of the rod extenders.

The $200+ price point is a bit tough though.

SizeGenetics Product Quality

SizeGenetics rod are made out of steel.

The plasic device parts that make up the frame of the extender are decent. The springs are also decent.

Like all springs, they will eventually wear out so a replacement SizeGenetics may be required.

It deserves a fair-to-decent review rating, in our opinion.

#4. Quick Extender Pro

quick extender pro

Quick Extender Pro is actually not that bad. But it ranks fourth on our list.

Quick Extender Pro is essentially a size toy like the Jes Extender and X4labs extenders.

But the PhalloGauge Extender is more popular than the Quick Extender Pro extenders.

There are a few problems with the Quick Extender Pro.

customer review of quick extender pro

In fact, it's probably the worst one out of the old length extenders.

One thing we will say is that the rod system is nothing special out of the rod extenders.

The $300+ price point is a bit tough though.

Quick Extender Pro Product Quality

Quick Extender Pro parts are made out of steel.

The Quick Extender Pro parts that make up the frame of the extender are decent. The springs are also decent.

Like all springs, they will eventually wear out so a replacement Quick Extender Pro may be required.

Don't forget to check out our full Quick Extender Pro review.

#5. X4 Labs Extender

The X4 Labs extender is another rod-extender.

However, there isn't much that makes it stand out compared to the other devices of the "rod" type.

Go here to read the full X4 Labs Extender review.

#6. PeniMaster Pro

The PeniMaster Pro is another extender that is similar to the PhalloSan Forte and the PhalloGauge Extender.

However, it is also one of the most expensive devices (over $300), and like the X4 Labs extender, it fails to stand out from the competition by offering suitable value with it's large cost.

Regardless, you can read the full PeniMaster Pro review here.

#7. Male Edge

The Male Edge extender is the same type of extender as the SizeGenetics, Quick Extender Pro, and Pro Extender.

Because it is so similar, there isn't much that makes it stand out from the other brands.

One notable difference is that the Male Edge comes in three different colors, which is nice.

It's price isn't very good compared to the others though.

#8. Jes Extender

The Jes Extender is just like all the rod extenders above (SizeGenetics, Pro Extender, Quick Extender Pro, and Male Edge Extender).

This is probably the first device that entered the market - you can think of it as the "grandpa" device.

However, as time went on, the other extenders began to exceed the quality of the Jes Extender, and the prices also became better.

That being said, if you want a slice of history in the extender market, to put in your personal collection, you can pick up a Jes Extender as a device souvenir.

15 Male subjects that used the PhalloGauge Extender gained an average of 30% in size.

(Data from PhalloGauge Medical Lab Fall 2018 study)



One of our latest participants aged 36, who ordered in October last year. After noticing a gradual reduction of his natural size due to his age, he thought there was nothing he could do.

He first tried pumps, then pills, and realised that they could only give temporary results. Some of them did nothing at all. He spoke to his Doctor about his size shrinkage issue who then recommend he try an extender. He reported "solid results" within the first 14 days and says his erection quality is far superior than it has been in recent years.

How to Use a Penis Extender

How to put on a pulling extender stretching system

  1. Make sure your unit is flaccid (ideally under 20% hardness)

  2. Fit the soft foam loop base against your pelvis, around the base of your shaft.

  3. Secure the top of your shaft (glans) in the gripping mechanism.

  4. Hook the gripping mechanism to the pulling belt.

  5. Adjust the tension - not too hard, not too soft.

Demonstration of how to use a penis extender (pulling-type).
An example of the PhalloSan penis extender (Pulling-Type)

How to put on a rod based extender system

  1. Make sure your unit is flaccid (ideally under 20% hardness)

  2. Fit the hard base against your pelvis, at the base of your shaft.

  3. Slide your tip into the noose.

  4. While holding your glans there, tighten the noose so that it clamps onto the upper shaft.

  5. Adjust the angle of the device.

Demonstration of how to use a penis extender (rod-type).
The top of the shaft is secured in the noose shown above.

How long should I use the penis extender each day?

That's a great and important question.

The typical recommended usage for each day is:

3 to 6 hours per day.
(Try to aim for at least 4 hours.)

Ane example of an all-day stretching routine: Start at 9am, Stop at 3pm.
Wear the extender during the orange highlighted times.

If you're a complete beginner you definitely don't want to train yourself too hard and risk stunting your growth from overstretching.

Thus, we would highly recommend that beginners just get used to the device for the first couple weeks and only stretch maybe two to three hours a day.

Because of the high hour requirement that is required by wearing enlargement devices, you have to plan your day around its usage.

See, the reason why you have to stretch for so many hours a day as compared to a 20 minute manual stretching exercise session is because when you use an extender device, you want to keep the average force lower compared to the force applied during manuual stretching.

In order to compensate for this lower applied force, you make up for it by simply stretching for a longer amount of time during the day.

This formula has been proven and there are clinical results backing it up.

Penis extenders also need to be cleaned periodically and can be done by using water and hand soap.

You really need to do this in order to remove body oils and dead skin cells off the device.

Cleaning them in this manner is really straightforward and is not difficult at all.

Daily Extender Routine

This is the most reliable, and easiest routine that you can follow, based on the 6 hour timing shown above.

It guarantees you get the necessary hours of stretching in and minimizes the burden.

  1. Put on the extender as part of your morning routine (like after brushing your teeth). Make sure to use the bathroom before putting the device on.

  2. Commute to work. Wear the device until lunch.

  3. Lunch break. Go to the bathroom and take off the device before you eat and keep it off while you eat. Feel free to relieve yourself at this point as well.


  4. Lunch break over. Go to the bathroom and put the device back on.

  5. Commute home. (The device is on until you finish work!)

  6. At home. Take off the device and relax! You're done with the routine. You don't have to worry about it for the rest of the day!

  7. Bonus step: Clean the device. Doesn't have to be done everyday just once every two weeks or so.

  8. Running water and soap over a penis extender to clean it.
    You should clean your extender at least once every two weeks.

The good thing about this routine is that you don't have to count the hours stretched.

That's because it was designed to revolve around your schedule.

This routine is typically for a regular weekday workday, but can be used for weekends as well.

In fact, it's even easier to do on weekends (more privacy)!

Safety

A quick note before we start.

Most guys think of their "thing" like a piece of gum.

It's not their fault, it's pretty instictive to think this - I even thought this is how it worked at first.

However, that's 100% not how it works.

Permanently damaging your body by trying gain size is not the correct way to do enlargement.

Maintaing a Safe Tension

Safety is obviously a very important factor when using an extender.

You don't want to burden your life by not being able to urinate, or have quality bedroom time - two very important things.

If we consider the only rule you need to follow, from a safety point of view, we'll see that it aligns perfectly with safety.

The rule essentially prevents you from pulling so hard as to permanently damage your thing.

That's because the desired pulling force is actually very gentle in nature.

Surgery Alternative

This is a common risk in penile surgeries.

Stimulating growth through traction stretching, is. We will see later on in this article how it works and why.

Just know that pulling hard leads to bodily damage and will not result in sustainable, usable size gains.

Why extenders are inherently safe

The pulling in of itself is not supposed increase length.

The pulling is supposed to be a stimulus that triggers cell hyperplasia, the true phenomenon responsible for growth.

Now consider what would actually happen if you were to pull too hard.

If you were to pull too hard, you would permanently dislocate certain ligaments and tissues from their "correct" place.

Sure, that would add length, but it would also damage your member.

See the length would be added due to healed damage , not by letting new cells grow naturally.

Ultimately, you would be hurting your ability to use the bathroom (pee) and probably just as worse, provide yourself to have the ability to get an erection - no good.

Damaging your precious thing permanently is not worth it.

Tips

Follow these tips and you'll never have to worry about penis extender safety again.

Only stretch slightly more than it takes to keep your thing fully elongated

If you don't take away anything else, but this, you will still be ages ahead of guys who are just starting out and have no clue what to do, what's effective for gains, or even what's safe.

That's this rule is so effective from different practical perspectives.

How long should to wear a device each day?

That's a great and important question.

The typical recommended usage for each day is about 3 to 6 hours, with 4 hours as a more specific recommendation.

If you're a complete beginner you definitely don't want to train yourself too hard and risk stunting your growth from overstretching.

Thus, we would highly recommend that beginners just get used to the device for the first couple weeks and only stretch maybe two to three hours a day.

Maintaing Your Results

Because of the high hour requirement that is required by wearing enlargement devices, you have to plan your day around its usage.

See, the reason why you have to stretch for so many hours a day as compared to a 20 minute manual stretching exercise session is because when you use the extender device, you want to keep the average force lower compared to the force applied during manuual stretching.

In order to compensate for this lower applied force, you make up for it by simply stretching for a longer amount of time during the day.

This formula has been proven and there are clinical results backing it up.

Extenders also need to be cleaned periodically and can be done by using water and hand soap.

Typical Prices

Unfortunately, penis stretchers are pretty expensive.

They typically cost you more than $150.

Some even go as high as $339!

Unfortunately, there are essentially the same device with no significant innovation or improvement over the past 20 years.

That is, they all consist of the same rod, noose and spring system.

While there are some slight differences from extender device to extender device, they are few and far in between.

So ultimately, it doesn't matter which extender device you use, because all that matters is it's ability to hold your precious thing in a light, stretched position for long periods of time.

However, if you're looking for the cheapest extender, you may want to read up on the different consequences of doing so.

If you want to try your hand at making your own homemade penis extender - warning, it's actually very hard to get right, and the materials are hard to come by.

Take a Break

All manufacturers recommend that you take a short break from wearing an extender - at least one break per week.

These breaks are crucial as they help prevent permanent damaging of the penile tissues.

In the worse case that you do get a penile injury, you're required to take a 3-7 days off to heal.

Shave Your Pubic Hair

It’s highly recommended that you shave your pubic hair before putting on a device in order to prevent pain from the device tugging on your pubic hair.

If you prefer not to do this, you can try trimming with clippers, or just acknowledge that there may be some irritation when the pubic hair gets caught in some of the parts of your extender device.

Make sure Penis is Completely Flaccid

Always ensure that when you decide to use an extender for an enlargement session, your unit is 100% flaccid.

If you stick your unit in a device while erect, it will not function properly.

In fact, it is impossible to increase your length and girth with a device if it is fully erect.

That means using a device with an erection is not effective and you'll be wasting your time.

Benefits

When you pull, the force is fixed, and cannot increase or decrease unexpectedly.

This is probably the biggest reason on why they're so safe.

Penis extenders are technically, machines, after all. They are programmed to apply a certain amount of force.

If they were to deviate from this desired force, then they would be just as inaccurate as exercises.

The secret with extenders' effectiveness is their consistency.

Now, given that extenders are machines, the only thing you need to do to guarantee safe usage is to make sure you follow the one rule we mentioned above when using an extender device!

From that point, you won't have anything to worry about.

Treating Peyronie's Disease

Peyronie's Disease is a medical disease when your penis curves when erect and is not straight.

While the disease is not life-threatening, it is the source of self-esteem issues as well as possibly increasing sexual intercourse difficulty.

It hss been clinically proven that extenders are effective treatments to treat the curvature due to Peyronie's Disease.

Generally, the time frame to see a reduction in curvature is on the order of 6 months to a year.

Extenders have been recognized by the medical commmunity to effectively treat symptoms from Peyronie's Disease.

Frequently Asked Questions

Can men wear a penis extender under their pants?

Depends on which one you buy. Some are better at this than others.

Most extenders are intended to be worn outside the home.

The best devices are not visible under your clothing. However, you should ensure that your device can both function and be hidden under clothing.

It can help to wear loose-fitting clothing to accomplish this.

Are Penis Extenders Safe?

Yes. When used correctly.

In fact, they are so safe, they are the preferred method of enlargement over surgery.

What is Penis Traction?

Clinical penis extenders work by utilizing the "traction principle", also known as "penis traction" or "penile traction therapy (PTT)".

The traction principle, put simply, involves keeping a body part in a "stretched" position for long periods of time.

The result?

A growth in body tissue size (Cell Hyperplasia)

The human body has a fascinating ability to adapt to the tension and experiences.

Cell hyperplasia means that the body cells split and double, thus increasing the total number of body cells.

This is effect is biological in nature and is theorized to contribute to the survival of the body tissue.

Diagram showing how cells duplicate in response to using a penis extender.

The traction force causes penile cells to divide - resulting in a net increase in tissue mass = physical size increase.


The end result is indisputable, permanent size gains simply due to increased net tissue mass.

How long should I use the device each day?

You should wear it for 6 hours each day.

Do penis extenders work?

Yes, extender size results will last forever, as concluded by the British Journal of Urology International.

See more penis extender results here.

How long until I see results?

Most male user reviews and clinical studies report that it only takes a couple weeks to start seeing results.

How long should men wear a device each day?

We recommend between 3-6 hours total, each day.

Will both flaccid and erect penile length increase?

Yes, both will increase.

Will I Lose My Size Gains If I Stop Using It?

No. The extender device increases the total number of penile cells so that added mass will stay permanently.

Can I wear a penis extender while sleeping?

Yes, if it doesn't disturb your sleep.

Can they add girth size gains?

No. The industry standard to enhance girth size gains is to use a penis pump.

Will I Get Weaker Erections?

No, it will actually enhance your male erections.

How Old Do You Have to Be?

You must be at least 18 years old.
